Abstract
A method for adjusting the damper hardness of a vibration damper of a wheel of a transportation vehicle, wherein the transportation vehicle body movement signal is generated by a control device of the transportation vehicle from a first sensor signal of the first sensor unit connected fixedly in to a transportation vehicle body, a wheel movement signal is generated from a second sensor signal of a second sensor unit which detects a wheel position of the wheel with respect to the body, a speed signal which describes a speed of the transportation vehicle body is generated based on the transportation vehicle body movement signal, and the wheel movement signal and an actuation signal for setting the damper hardness is generated based on the speed signal. The transportation vehicle body movement signal is filtered by a first filter unit and/or the wheel movement signal is filtered by a second filter unit.
